IMPROVEMENT lN STEAM-JET BOILER-TUBE CLEANERS.

The Schedule referred to lu these Lettersv Patent and making part of thelame. l

To all whom it may concern.- Y

I, ROLAND G. HUSSEY, Of Milford, iu the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inTube-Cleaners, of which the following is a specification.

Nature and Object of the Invention.

The nature of my invention consists in arranging a steam-nozzle in sucha manner that the steam blast will issue Afrom it with 'a spiral motion,and thus act lupon the inside of a ne in the most effectual manner, theobject being to providea simple and cheap device for cleaning tubes andue's of steam-boilers.

the handle E and' flexible tube F is attached. v F' is a tube, whichserves to conductr steam from i any convenient point on the boiler tothe-tube D F.

B is a cylindrical tube attached to the end of the tube D, asfshoivn.-

C is a. flange, which. serves as a stop to rest against the tube-sheetwhen the part B is inserted into the I tube for us.

Within the external tube D B, I aix the cylindreconi'cal piece A A', inform as shown in fig. 2.

rlhis part may be connected to the external part n a variety of ways,but I prefer to fasten it by means of 4three radial arms, e e e, asshown in g.' 3.

The part A is provided with spiral ribs, a a a, &c., as shown in fig. 1,or, if desirable, these ribs may be on the inside 'of the tube B.

The operation of my invention is as follows:

The cleaner is so placed that the'part B enters the tube to be cleaned,the ange C resting upon the tube` sheet. Then steam from the boiler islet in through the conducting-tube F'. y

The rushing steam is divided by the cone A, so that as it passes throughB it is in the form 1of a hollow column, annular in Section, but thespirals a a, &o., give it a rotary motion, which, in connection Awithits forward motion, renders it very edectlive in cleansing the tube.

The handle may be made longer or shorter, and, if desirable, be jointedor bent to suit different styles of boilers.

I claim as my invention-f- The combination of the tube D B with thecentral.l

piece A A', and the spiral a al a?, arranged substantially asdesoribed,and for the purpose set forth.
